Dichlorodiphenyltrichloroethane (DDT) Dichlorodiphenyltrichloroethane (DDT) is an insecticide used in agriculture. The United States banned the use of DDT in 1972, but some countries still use the chemical.
This will require scientific and technical resources that developing countries lack, but which Western countries can offer. We therefore advocate eliminating DDT in two phases. Phase one would immediately ban DDT use in agriculture, but would make an exception for the life-saving use of DDT in malaria control. Phase two would extend the ban to public health uses of DDT, but ONLY if Western countries research and successfully implement effective, affordable alternatives to replace DDT.
